wat gains if any are got by constant vtec say like havin it on a switch

 

TODA vtec killer cams?

 

it will be kinda the same job i was just searchin the net and see this can be done and woundered wat gains can be had ive buddyclub spec3+ cams and buddyclub valve train

 

You will see no gains at all. You will lose bottom end, your car will be slower, and most likely barely idle unless you have some sort of engine management..
Youll probably find more info in the tech/misc forum. Id search there if I were you...

 

Set vtec to 2k. LMAO

 

You can't just lower VTEC without knowing what else it invloves. Do some research and you will see why this will not benefit you.

 

if i was to do it id be gettin it mapped and properly set up i jus wanna know would the be any benefits

 

Someone don't know what VTEC is....

He jus knows it be like BWAAAAH!
Lol

Merry christmas n holidays guys

 

LMAO!

 

You too brother. Have a Happy VTEC-ish Christmas

 

I had a friend that had VTEC set to 4k and he thought it was bad *** that it hit that low. I rode in the car and he did a 1-2-3-4 down the road. I said swing by my house real quick so I can grab my laptop. Did some street tuning and the sweet spot was 5500RPM. He did another 1-2-3-4 and goes holy **** thats way faster! You have to look at when your primary lobes stop making power, a lot of times switching to the bigger lobe lower in the RPM range will put a dip in the curve until it picks up more RPM. The point in tuning is to not have a dip in the curve at all if you can. To actually have a constant VTEC lobe you would have to lock the pins because remember it relies off oil pressure.

 

I'm sure there's not enough oil pressure at idle and lowering it anything below 3k probably isn't a good idea.

 

There are things you can do to raise the oil pressure, that's irrevelant.
Anyone who knows why vtec was made and how it works wouldn't eliminate it.
Why do you guys think ford, toyota, nissan, and other manufacturers are using it now too?

 

The reason to run vtec killer cams is so you can take out all the vtec parts so the valve train is lighter and you can rev higher and more reliable

 

They are only for race engines that spend most of their time above 5k

 

i have VTEC set at 3800, only because when i tuned it the idle cam stopped making power at that RPM, power delivery is a lot smoother and the lower end torque is very useful, only bad thing i can think of is the VTEC engagement barely noticable..in relation to OP thread, you will lose a substantial amount of power and torque, and probably have **** petrol usage..

 

What cam are you using?
did you check what your oil pressure is when vtec engages?

 

 

just my stock GSR cams and i have no idea about my oil pressure sorry

 

Your oil pressure is most likely low while vtec engages. And maybe im wrong but I don't think you should be losing power at 3800 on stock cams. Where did you tune it?

 

I can provide you the dyno print out before and after mods to show you the drop off in power at that RPM..i tuned it on a very reputable and professional dyno, the power curve is so smooth, virtually no down or up 'bumps' in power anywhere throughout the rpm range.

 

Hmmm what are your mods?
